Foodborne diseases are caused by indigestion of contaminated food. In some cases they may result in either hospitalization or death. The Centers for Disease Control (CDC) and Prevention in 2017 stated that 10% reduction in foodborne illness would prevent nearly five million illnesses every year. Approximately one out of six Americans become ill from contaminated foods or beverages every year. Another problem is drug resistance which is responsible for approximately 2 million illnesses and around 23000 dead every year. Nearly 400,000 Americans acquire antibiotic-resistant or each year. The aim of this study was to evaluate the outbreak of salmonellosis and shigellosis along with their antibiotic susceptibility patterns in different provinces of Iran. Over a period of 2 years from 2015 to 2016, a total of 1055 cases in 249 outbreaks reported in 20 provinces of Iran, as a part of surveillance by the National Institute of Health (NIH). The stool samples of patients were taken and tested for and by conventional standard techniques. Disk diffusion was used for the antibiotic sensitivity test. Of 1055 cases, 118 (11.2%) contained and 74 (7%) contained . Antibiotic susceptibility tests showed that entirely 100% of and isolates were susceptible to ciprofloxacin; whereas 12.2% of and 98.2% of were resistant to cotrimoxazole. Our results show that there is a need for more food handling practices to minimize the exposure of consumers to and , at all points along the distribution chain.
食源性疾病是由食用受污染食物消化不良引起的。在某些情况下，它们可能导致住院或死亡。疾病控制与预防中心（CDC）在2017年指出，食源性疾病减少10%每年将预防近500万例疾病。每年约六分之一的美国人因受污染的食物或饮料而患病。另一个问题是耐药性，每年约有200万例疾病和23000人死亡与此有关。每年有近40万美国人感染耐抗生素菌。本研究的目的是评估伊朗不同省份沙门氏菌病和志贺氏菌病的暴发情况及其抗生素敏感性模式。在2015年至2016年的两年时间里，伊朗20个省份共报告了249起暴发中的1055例病例，这是国家卫生研究所（NIH）监测的一部分。采集患者的粪便样本，采用传统标准技术对沙门氏菌和志贺氏菌进行检测。采用纸片扩散法进行抗生素敏感性试验。在1055例病例中，118例（11.2%）含有沙门氏菌，74例（7%）含有志贺氏菌。抗生素敏感性试验表明，所有沙门氏菌和志贺氏菌分离株对环丙沙星均敏感；而12.2%的沙门氏菌和98.2%的志贺氏菌对复方新诺明耐药。我们的结果表明，需要采取更多的食品处理措施，以尽量减少消费者在分销链的各个环节接触沙门氏菌和志贺氏菌的机会。
